Setting the Concrete Pad
•
The soil must have the following capabilities:
•
Allowable bearing pressure: 1000 psf
•
Lateral bearing: 150 psf
•
Coefficient of sliding: 0.25
•
The GREEN MACHINE must be installed on a concrete pad, on grade, and permanently
anchored to the concrete pad.
•
Install the concrete pad level.
•
Use steel re-enforced rebar in the pad for additional strength.
•
The GREEN MACHINE CANNOT be installed directly on or anchored directly to
asphalt. It must be installed and anchored directly to a concrete pad.
•
The GREEN MACHINE can be installed on an existing concrete pad, provided:
•
The existing concrete is of sufficient strength and thickness to support the GREEN
MACHINE.
•
VST recommends a minimum of 6” thick concrete to accommodate 3
-
1/2” –
4”
expansion-type anchor bolts.
•
Cracked concrete without re-bar may NOT be of sufficient strength to properly
support the GREEN MACHINE.
•
The GREEN MACHINE is installed level.
•
NOTE: VST CANNOT BE HELD RESPONSIBLE FOR DAMAGE CAUSED BY IMPROPER
GREEN MACHINE FOUNDATION SUPPORT.
•
VST does not provide any hardware to install the GREEN MACHINE on the pad.
•
VST recommends using an 18
” minimum clearances around the perimeter of the
GREEN
MACHINE for maintenance and service.
•
Concrete pad minimum dimensions:
•
42” long x 30” wide
•
6” thick (minimum)
•
See Figures 1-2 and 1-3
•
Install expansion-type bolts after completing the concrete pad. The bolts must be:
•
3/8” diameter
•
Embedded 3-
1/2” to 4” into the slab
•
Extend approx. 1-
1/2” above the top of the slab
